Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flaw detectors, and particularly relates to an automatic ultrasonic flaw detector. Background Art
[0002] An ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument that uses ultrasonic technology to detect internal defects in materials.
[0003] When an ultrasonic flaw detector uses ultrasonic waves to propagate in a material and encounters defects (such as cracks, porosity, air holes, inclusions, etc.), it will produce reflection, refraction or waveform conversion. By detecting and analyzing these reflected waves or transmitted waves, the internal defect situation of the material can be evaluated. Its basic principle is to generate an excitation electrical signal through a circuit to drive a crystal with piezoelectric effect (such as quartz, lithium sulfate, etc.) to vibrate, thereby generating ultrasonic waves. After the ultrasonic waves propagate in the material and encounter defects or interfaces, they will be reflected. The reflected waves are received by the piezoelectric crystal of the probe again and converted into electrical signals, and finally an image is formed through a signal processing circuit for people to observe and judge.
[0004] Existing ultrasonic flaw detectors still have the following disadvantages. When detecting steel pipes or other metal pipes produced in a processing factory, using common ultrasonic flaw detection equipment requires manual back-and-forth movement of the ultrasonic probe on the metal plate, which is time-consuming and laborious, with low detection efficiency and easy to miss detection.
